Abstract

A supply circuit for an implantable medical device (IMD) is presented. The supply circuit includes a battery, a high current circuit, a current-modifying component, a low current circuit, and a capacitor. The low current circuit is connected to a first terminal of the battery. A current-modifying component is connected to the battery, a capacitor, and to a high current circuit.
